Chaotic oscillations in a map-based model of neural activity
Maurice Courbage, V. I. Nekorkin, L. V. Vdovin
We propose a discrete time dynamical system (a map) as phenomenological model of excitable and spiking-bursting neurons. The model is a discontinuous two-dimensional map. We find c…
Multiphoton Transitions in a Spin System Driven by Strong Bichromatic Field
A. P. Saiko, G. G. Fedoruk, S. A. Markevich
EPR transient nutation spectroscopy is used to measure the effective field (Rabi frequency) for multiphoton transitions in a two-level spin system bichromatically driven by a trans…
Radiative Strength Functions for Dipole Transitions in 57, 59Co
S. S. Ratkevich, I. D. Fedorets, B. A. Nemashkalo +1
Average-resonance data on the (p,gamma) reaction on 56,58Fe that were taken at proton energies of Ep=1.5-3.0 MeV are used to determine the absolute values of the radiative strength…
High-pressure effects on the optical-absorption edge of CdIn2S4, MgIn2S4, and MnIn2S4 thiospinels
J. Ruiz-Fuertes, D. Errandonea, F. J. Manjon +4
The effect of pressure on the optical-absorption edge of CdIn2S4, MgIn2S4, and MnIn2S4 thiospinels at room temperature is investigated up to 20 GPa. The pressure dependence of thei…
Spin Frustration and Magnetic Exchange in Cobalt Aluminum Oxide Spinels
N. Tristan, V. Zestrea, G. Behr +5
We report on x-ray diffraction, magnetic susceptibility, electron- spin resonance and heat- capacity studies of Co[Al_1-xCo_x]_2O_4 for Co concentrations 0<x<1. In this spinel syst…
LIGO: The Laser Interferometer Gravitational-Wave Observatory
The LIGO Scientific Collaboration, B. Abbott
The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves of astrophysical origin. Direct detection of gravitational wa…
Diameter-dependent thermopower of Bi nanowires
A. Nikolaeva, T. E. Huber, D. Gitsu +1
We present a study of electronic transport in individual Bi nanowires of large diameter relative to the Fermi wavelength. Measurements of the resistance and thermopower of intrinsi…
Control of laser wake field acceleration by plasma density profile
A. Pukhov, I. Kostyukov
We show that both the maximum energy gain and the accelerated beam quality can be efficiently controlled by the plasma density profile. Choosing a proper density gradient one can u…
Multifractal spectrum of phase space related to generalized thermostatistics
A. I. Olemskoi, V. O. Kharchenko, V. N. Borisyuk
We consider a self-similar phase space with specific fractal dimension being distributed with spectrum function . Related thermostatistics is shown to be governed by the…
Polar phonons and spin-phonon coupling in HgCr2S4 and CdCr2S4
T. Rudolf, Ch. Kant, F. Mayr +3
Polar phonons of HgCr2S4 and CdCr2S4 are studied by far-infrared spectroscopy as a function of temperature and external magnetic field. Eigenfrequencies, damping constants, effecti…
Incoherent mid-infrared charge excitation and the high energy anomaly in the photoemission spectra of cuprates
S. Cojocaru, R. Citro, M. Marinaro
On the basis of a semi-phenomenological model, it is argued that the high energy anomaly observed in recent photoemission experiments on cuprates is caused by interaction with an o…
Radiative Losses in Plasma Accelerators
I. Kostyukov, E. Nerush, A. Pukhov
We investigate the dynamics of a relativistic electron in a strongly nonlinear plasma wave in terms of classical mechanics by taking into account the action of the radiative reacti…
Evidence for local lattice distortions in giant magnetocapacitive CdCr2S4
V. Gnezdilov, P. Lemmens, Yu. G. Pashkevich +6
Raman scattering experiments on CdCr2S4 single crystals show pronounced anomalies in intensity and frequency of optical phonon modes with an onset temperature T*=130 K that coincid…
Spin-phonon coupling in antiferromagnetic chromium spinels
T. Rudolf, Ch. Kant, F. Mayr +3
The temperature dependence of eigenfrequencies and intensities of the IR active modes has been investigated for the antiferromagnetic chromium spinel compounds CdCr2O4, ZnCr2O4, Zn…
